1. A system comprising:
- a risk calculation system programmed to calculate a risk based on a static input and a dynamic input; and
a decision support system programmed to use the risk to derive a decision; and
a plant control system programmed to update operations of a plant based on the decision, to observe a plant system, and to store plant system observations as historical data, wherein the decision predicts future plant conditions, wherein the static input comprises a business environment data, wherein the dynamic input comprises a signal representative of an unexpected maintenance event, and wherein the plant control system is configured to analyze the signal representative of the unexpected maintenance event and the historical data to credit the unexpected maintenance event in lieu of performing an equipment test event related to the plant system.

10. A method, comprising:
-
observing a plant system via a plant control system; storing plant system observations as historical data via the plant control system; determining, via the plant control system, an occurrence of an event based on an event rule and a dynamic input associated with at least one component of a plant wherein the event comprises an unexpected maintenance event; and responding, via the plant control system, to the occurrence of the event, if the event occurs, wherein responding comprises; updating a risk projection based on at least one dynamic input; updating a risk threshold based on at least one static input; determining whether the risk projection exceeds the risk threshold; determining a first action if the risk projection exceeds the risk threshold, wherein determining the first action comprises selecting a mitigation action as the first action if one or more mitigation actions are available, or determining a recommended action as the first action if no mitigation actions are available; determining a second action if the risk projection does not exceed the risk threshold, wherein determining the second action comprises calculating a next scheduled action as the second action, wherein the mitigation action comprises using a backup component configured to operate as a backup to the at least one component; and analyzing, via the plant control system, the unexpected maintenance event and the historical data to credit the unexpected maintenance event in lieu of performing an equipment test event related to the plant system. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
